<p>Yes @IvyHopeful , on my test there was only one question on which you HAD to have a graphing calculator.
It dealt with setting up a linear regression. You could have done by guessing and eliminating answer choices though. I believe it is very possible to get an 800 without a graphing calculator. I dont remember using mine on the test (besides basic scientific calculations) except on this question and maybe i used it once to double check on a question which asks you where does this expression intersect blah blah. And i got an 800. Even my friend had not used one and he got an 800! So dont worry! But if you can maybe borrow from someone, i would definitely use it!
